Hoʻolauna

ʻO 2-methylpyridine kahi mea hoʻohuihui. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me kahi ʻala e like me pyridine.

 

Hoʻohana pinepine ʻia ka 2-Methylpyrazine i ka synthesis organik ma ke ʻano he reagent, solvent a me waena. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no nā catalysts no nā hopena metala-catalyzed.

 

Aia nāʻano likeʻole no ka hoʻomākaukauʻana i ka 2-methylpyrazine,ʻo kekahi o nā mea i hoʻohana pinepineʻiaʻo ia ka hopena o ka 2-aminopyrazine me nā methylation reagents e like me ka methyl iodide. ʻO nā ʻano hana synthesis kūikawā pū kekahi me ka hydrogenation cyanide a me ka halogenation o ka halogenation.

I ka wā e hana ai, pono e lawe ʻia nā ʻano hoʻoheheʻe maikaʻi e pale aku i ka hoʻohu ʻana i nā kinoea a i ʻole ka pili ʻana me ka ʻili a me nā maka. Hōʻalo i ka hoʻopili ʻana me nā oxidants ikaika a me nā waikawa e pale ai i nā hopena ʻino. Inā loaʻa ka pilikia a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau.
